Abstract To maintain sensitivity of the sensor, especially infrared band liquid nitrogen is needed for cooling during imaging process airborne hyperspectrometer. However, traditional filling requires a lot manual intervention, which not only time-consuming and labor-intensive, but also creates great potential safe hazard aviation operations. In view this, this paper designs an hyperspectral aut...

Developing a computational representation for electromechanical devices that supports conceptual synthesis of complex devices from simpler subsystems both in terms of device behavior and form has been of serious interest. Proposed approaches in literature consider either the synthesis of device behavior or only of shape depending on the limitations of the device model and computational approach...

MEMS (Micro-electromechanical Systems) becomes important increasingly due to the smarter and smaller fuze used in OICW (Objective Individual Combat Weapon). MEMS Safety and Arming (S&A) device is employed in different platforms and regions for small caliber projectile. Therefore, it is necessary to make a parametric study of the MEMS S&A device in different apply environments and explore the ma...

Field studies have demonstrated that it is possible to evaluate the state of many shipboard systems by analyzing the electrical power that is drawn by electromechanical actuators (Ramsey et al. 2005, DeNucci et al. 2005, Cox et al. 2006, Cox et al. 2007). This paper demonstrates how a device known as a non-intrusive load monitor (NILM) uses only electrical power data to detect several critical ...

This paper presents a microfluidic pumping approach using traveling-wave dielectrophoresis (twDEP) of microparticles. With this approach, the flow is generated directly in the microfluidic devices by inducing strong electromechanical effects in the fluid using integrated microelectrodes. The fluidic driving mechanisms due to the particle-fluid and particle-particle interactions under twDEP are ...

A microelectromechanical system (MEMS) sound waveguide is considered as a transmission line for RF signals. We analyze a device geometry of a straight one-dimensional microsize silicon rod, where a longitudinal acoustic wave is generated and detected using capacitive transducers. Linear, isotropic, and nondispersive acoustic-wave propagation is assumed. Based on the calculation of the electrome...

This paper deals with the study of a model of self-sustained electrostatic micro Electromechanical system (MEMS). The electrical part contains two nonlinear components: a nonlinear resistance with a negative slope in the current-voltage characteristics and a capacitor having a cubic form as the charge-voltage characteristics. The modal approximation and the finite differences numerical scheme a...

In Korean medicine, pulse diagnosis is one of the important methods for determining the health status of a patient. For over 40 years, electromechanical pulse diagnostic devices have been developed to objectify and quantify pulse diagnoses. In this paper, we review previous research and development for pulse diagnostic devices according to various fields of study: demand analysis and current ph...
